A temporary disruption of the body's biological clock experienced by persons who stay awake all night chatting on the Internet to someone resident in another time zone (typically a person they have never met and never will). The effects of net lag, which may include fatigue and irritability, generally disappear soon after one's partner discovers the conversation history in the messaging application.

The delay experienced as news moves from the internet to newpapers magazines and television. News appears first in the fastest, unintermediated media like blogs and wiki's. All other media are slower, hence the lag. The surprise you feel when you read todays newspaper after surfing the web, and you realize it yesterday's news.

the sum of jet-lag-like symptoms caused by watching a series of matches (e.g. the FIFA World Cup) live, in the small hours of the night, due to major national time differences, over a period of days or weeks (with "net" referring to the net in soccer, or tennis, or volleyball, etc.)

There are still two late-night World Cup matches to watch! Football has caused me a lot of very late nights this month, and I'm blooming knackered, suffering from an acute case of "net lag"!
